CONFIG_KALLSYMS
Say Y here to let the kernel print out symbolic crash information and
symbolic stack backtraces. This increases the size of the kernel
somewhat, as all symbols have to be loaded into the kernel image.
CONFIG_KCORE_ELF
If you enabled support for /proc file system then the file
/proc/kcore will contain the kernel core image. This can be used
